Are there any risks or side effects of AAC?

When a child uses pictures, signs or a speaking device to be understood, parents often ask: could this hold back their talking? The reassuring evidence says no.

In short

Augmentative and alternative communication (AAC) — picture boards, sign, or speech-generating devices — is safe and carries no medical side effects. The biggest worry parents have is the myth that AAC stops a child from speaking; decades of research show the opposite: AAC tends to support and often increases spoken words, because it lowers frustration and gives a child a reliable way to connect. The real risks are practical, not harmful — choosing the wrong system, abandoning it too soon, or not training the family — and a skilled speech therapist prevents these.

The honest picture of "risks"

AAC is not a medicine, so there are no physical side effects. What to be aware of instead:

• The "it will stop speech" myth — this is the commonest fear and it is not supported by evidence. AAC gives a child a voice now and frequently encourages more vocal attempts, not fewer.
• Wrong fit — a system too complex (or too simple) for a child's current abilities can cause frustration. The right match comes from proper assessment, not guesswork.
• Abandonment — devices or books get set aside if the family and school aren't shown how to use them daily. Consistent modelling by adults is what makes AAC succeed.
• Over-reliance on prompting — if a child is always physically guided, they may wait to be prompted. Good therapy fades support so communication becomes the child's own.
• Frustration during the learning curve — early days can be slow; this settles with patience and coaching, and is far gentler than the frustration of not being understood at all.

None of these are reasons to delay AAC. They are reasons to begin it with a qualified team who reviews and adjusts the system as your child grows.

When to seek guidance

If your child struggles to be understood, gets frustrated when communicating, or speech is significantly delayed, a speech-language assessment helps decide whether AAC could help and which type suits your child best. AAC is introduced and reviewed by a speech therapist — never bought blindly online — so it stays the right fit over time.
